I have a suggestion for MergeGlyphs as well. It would be very helpful if MergeGlyphs showed the “Last Changed” timestamp for each glyph or, even better, a visual indication of the most recent version of the glyph.
I’m working on a project with 2 other people and each one of us works on our own copy of the file. Having the timestamp or a “most recent” flag would streamline the merging process.
